AI Technical Summary

Technical Problem

Cross-linked polymer materials from electrical cable production and end-of-life cables are not recyclable, leading to significant waste and disposal costs, as they cannot be reshaped by conventional thermomechanical processes.

Method used

Utilize ground cross-linked polymer particles as a solid filler in the insulating layers of electrical cables and accessories, creating a composite polymer layer with a homogeneous dispersion throughout the polymer matrix.

Benefits of technology

Transforms waste cross-linked polymers into a high-value product, reducing environmental impact and costs associated with disposal, while maintaining electrical performance.
